Mövenpick Restaurant

Christiani Wassertechnik GmbH
Reference Letter
Dear Sir,
Our Mövenpick Restaurant opened in January 2000. After a short period, we noticed a high level
of limescale developing on the ice-cream makers. These calcifications could only be cleared bit by
bit which is a time-consuming process. To avoid potential losses, a short-term limescale filter was
installed. The operating time of this filter is limited however and thus resulted in high costs.
At a trade fair visit, we consulted the company Christiani Wassertechnik GmbH about other possibilities.
We installed the limescale converter Vulcan 5000 and the ice-cream makers have been functioning
smoothly for 10 months now.
The limescale, which accumulates especially in the crushed ice makers, can now be easily removed
as it is converted into fine-grained structures.
We wish the company Christiani further success with their excellent products.
Yours Sincerely,
Marcel Charrier
Director

Dear Mr. Christiani,
Thank you very much for your service to ”McDonald‘s Ukraine Ltd.”
From our side, we‘re very grateful for your cooperation and support throughout the
last 10 years.
Our company began to operate in Ukraine in 1987. Since then, we‘ve already opened
57 McDonald‘s restaurants.
In all of these restaurants, we have installed the Vulcan Descaler by CWT International,
which has delivered consistent results throughout each site.
The Vulcan range is easily installed and has been a very useful addition to our
company.
I would like to add that the support of CWT International is very important to us here
at McDonald‘s Ukraine.
Best regards,
Eugene Molodid

TA Truck Stop (Moriarty, New Mexico)
USA
Moriarty Travel Center
Here in Moriarty N.M. we have extremely hard water.
In our truck stop we have to always clean up after it.
The showers are a particular problem. From clogged
shower heads, to constant cleaning and scrubbing to
keep them clean.
It also wreaks havoc with the boilers and water heaters.
After Andy and Vulcan Water Products installed the
S100 unit on the main line, we noticed real soon, that the
showers were becoming cleaner, and the discoloration
in the water was gone too!
In our Country Pride restaurant, they noticed a dramatic
change in the color and clarity of the iced tea and
coffee, cleaner, spotless glassware and dishes, and the
ice machine makes clean ice! We are very pleased with
the results. Thank you Vulcan!

Kitchen of Spokane School
USA
Vulcan in a School Kitchen
Dear CWT Team,
The steam convection oven has greatly improved since
the installation of the Vulcan. The water is injected via
the pipe in the centre of the heating coils and a fan inside
the coils blows the water through the coils and comes
out as steam. The operating temperature of this device is
350F (180°C). The white material you see on the coils is
a powder coating that is easily removed with a wet cloth.
No more chemicals are required to clean the convection
oven.
However, we have noticed even greater results in the
school kitchen, which was previously using a traditional
water softening system. But all in all, we can confirm the
effectiveness of the Vulcan treatment, which means less
work for the maintenance staff.
The Vulcan unit installed on the entire building system
has also been extremely effective. No more rusty water
after weekends and Christmas break. The next Vulcan
will be installed on the other school buildings, which are
around 20 – 25 years old.
The last Vulcan unit is installed on the main cooling tower
– we have had nothing but positive news in regards to
this installation. We will be seeing more orders coming
from this customer very soon.
Best Regards

For treating water in the cookery on the fifth floor, Vulcan is
installed on the vertical piping in the warehouse where the
nearest main water pipe is exposed. The effectiveness of the
Vulcan appears in all the service water on the fifth floor that is
supplied through this piping.
Verification of the effectiveness
Grease trap under the countertop
The status of the grease trap upon installation of the Vulcan
was confirmed, and the changes of the statuses were
observed for approximately five months from the start of
the operation. In almost all cases, the effectiveness can be
confirmed through the observation for about 3 months.

The portions usually being contacted with
the treated water are cleaned easily with a
water flow from the tap.
The status after being used without cleaning
since the installation in June (no adhered
materials are seen on the portions usually
contacting with water).
Grease trap was cleaned with water flow
under the sink.
Similar effects have been reported at drainages in food factories, restaurants and kitchens. Many Vulcan installations showed that
the treated water had substantial cleaning effect even with extremely reduction of conventionally used detergents. There were
even some cases where the use of detergent (such as cationic detergent) causes a buildup of a thin film of dirt. Cationic detergents
should not be used. With the portions that do not contact with the treatment water, this effect cannot be expected. Vulcan has no
effect of breaking or resolving solids in drainage. Although the Vulcan has no disinfection effect, its prevention of dirt from adhering
to the basket and the net contributes to the reduction of mold‘s food source.

Vulcan for Grease Traps
3 Months Test Report
in a cake factory in Kanagawa, Japan
Vulcan has a trouble free design and easy installation. The LED light
always blinks dependably as it shows the processing conditions.
I have compared the state of the grease trap before and after
installing the Vulcan. Before installation, I noticed strong odors
when opening the hole. When I opened the hole one month after
the installation, no such odors were present.
As for the cleaning intervals, monthly cleaning may now not be
required. The effect and cleaning intervals of Vulcan will require an
annual observation, however, I believe the amount of cleaning will
be reduced remarkably.

of the Vulcan system, no cleaning process was
carried out before installing the Vulcan S10.
The scale has been completely turned into powder,
so there is no need to open it for cleaning, just by
operating the regular drainage function, it can keep
the hot water tank clean and free of scale. Due to the
good results, the cooperation will also be carried out

Installation purpose
The results
One month after the Vulcan S10 was installed, we
opened the sewage outlet of the Chinese kitchen,
and found that the scale scrap came out. At the
same time, we compared the sewage outlet of the
western kitchen without Vulcan, there is no scale
coming out. The hotel manager is very satisfied
with the results and is making a new purchase.
The two steamers in the Chinese kitchen had been
scaled badly, they had been corroded and damaged
in 2 years. The client used to clean with acid once a
month, but the steamed food had the taste of citric
acid, and the acid would even damage the equipment.
Therefore, the client is looking for an efficient way to
remove the scale without bad odour after cleaning.
Vulcan S10 was installed on the main water line of the
Chinese kitchen.
The scale scrap came out of the steamer in the Chinese
kitchen.

With a desire to replace chemicals, they are looking
for physical water treatments and fi nd Vulcan. After
installing Vulcan S500 unit, their heat exchanger
always stays clean without any chemicals.
Here is the comment of the chief engineer: “The
results are positive. We have recorded condenser
approach value for 2 to 6 months after cleaning the
tubes of the condenser, and there was a signifi cant
decrease on our chillers’ condenser approaches. Our
cooling towers remained clean and some of the stockup

Barcelo Bavaro Palace
Dominican Republic
The 5-star Barceló Bávaro Palace hotel is one of the top luxury hotels in Punta Cana, designed specifically for people who
love constant sunshine, the gentle sound of the Caribbean breeze whispering in the palm trees, and beautiful crystal-clear
waters with a coral reef. The hotel is beside one of the 10 most stunning beaches in the world.

Models: 2 x S100 in hotel’s main hot water lines
3 x S250 for cooling towers
4 x S500 for cooling towers
Installed by: InterClima
Installation purpose
Most of the hotels in the area of Bávaro/Punta Cana in
eastern Dominican Republic depend on ground water wells
for their domestic water supply, using traditional water
softening equipment to reduce the scale and hardness of
the water. The fact is that some of these resorts have very
poor maintenance resulting in extensive scaling of cooling
towers and domestic hot water piping and equipment.
The results
The project began with a mechanical room energy
audit resulting in a great opportunity to upgrade the
existing equipment with a very short payback period.
The original installation was sold with an estimated
payback of less than 2 years. To our customer’s happy
surprise, the actual payback was 9 months! The hotel
maintenance manager is very impressed with the
performance of the Vulcan systems, this opened up
many additional opportunities including the subsequent
chiller and cooling tower replacements.
Before Vulcan S100 was installed in hotel’s main hot
water line, the storage tanks had a solid 3 cm thick
scale layer inside them and the pumping pressure from
the booster set was at maximum while being unable to
deliver adequate water pressure to the end of the line
hotel rooms. After the 3 months period, an inspection
of the inside of the storage tanks revealed that the
scale layer was soft allowing them to mechanically
clean them removing most of the calcium deposits.
Other the following 12 to 18 months, the distribution
lines also cleared up resulting in much improved flow
and lower pumping costs from the booster sets.
The manager was instrumental in the approval of the
resent trial installation of an S250 in the Royalton White
Sands (Jamaica). We will continue to use the Barceló
success in our future presentations.

Reason for Vulcan installation
Engineering had to manually remove scale from pumps,
valves, kitchen equipment and from the 102 individual
electric hot water heaters every 6 months because the
property relies entirely on hard ground water which caused
signifi cant scale issues year after year.

Result installation of Vulcan S25
The Chief Engineer reported after an initial 6 months
following installation of the electronic anti-scale system
Vulcan S25 they were able to easily flush out already
dislodged scale from each tank heating unit – instead of
scraping away hard scale from the elements. After a second
inspection the units were found to be almost entirely free of
scale. Future inspections have now been reduced to annual,
random inspections only – which is felt to be suffi cient to
ensure overall domestic water piping system cleanliness.
Anti-Scale System Vulcan S25 installed
Inspection after 6 months
One of the water heaters at a Sea View Bungalow (photo)
was opened for inspection and showed much dislodged scale
particles at the bottom of the tank, with some easily removed
soft scale still present on the element only. This water heater
unit had not been scheduled for random inspection since
installation of the Vulcan unit at the Resort.
Additional benefits reported
The General Manager and CE reported that shortly after the
Vulcan had been installed, the linen being washed at the
inhouse Laundry plant was softer and whiter. In addition,
Food and Beverage staff reported brighter glass ware
with the detergents working much better. Housekeeping
staff reported that the usual white spots on bathroom tubs,
counters and floors had entirely disappeared and that outlets
of showers and taps needed no longer special attention with
only basic wiping being suffi cient to maintain their shine.
The little remaining scale is soft and easily fl ushed
out since installation of the Vulcan Anti-Scale System.

2. To remove the existing scale
3. To eliminate the need for chemicals or time-consuming

4. To reduce energy costs
Ackuritlabs, Inc.
History
The maintenance for these cooling towers previously involved continuous
injection of descaling chemical cleansers. The use of these cleansers was
discontinued over a year prior to the installation of the Vulcan. In that time, the
cooling tower flutes became encrusted with both scale and biofilm. Throughout
the time period described below, there were no cleaning procedures in place
with these cooling towers besides the treatment provided by the Vulcan.
Observations over time after the Vulcan installation
Vulcan S250 installed on a 10 inch diameter line
that feeds twin cooling towers (CT-1 and CT-2)
After 2 weeks, the green biofilm had begun to recede and gradually disappear.
After 3 weeks, the green biofilm had been further reduced and the scale
deposits had begun to separate from the flutes in coin-sized flakes.
After 1 month, the green biofilm had almost completely disappeared from
the surfaces in contact with the Vulcan-treated water. The flakes of scale
previously observed had fallen off in most places. The cooling tower flute
surface area covered with scale deposits had been decreased by over 60%.
The Vulcan does not change the water quality beyond its affect on its
propensity to cause scale buildup. The pH, conductivity, dissolved oxygen level,
and turbidity remained relatively constant during observation from before the
installation to over a month after.
We are very optimistic about continued improvement with Vulcan.

areas that still have some remaining green biofilm.

Dear Christiani Wassertechnik GmbH (CWT),
Due to the shower head scaling problem in Changping student dormitory in
Beijing University of Chemical Technology, the water was getting reduced after a
month, and the shower head was blocked completely after two to three months.
The scale was very hard, so we even had to use the 1.8mm driller to remove
it. In addition, the drinking water heater in the student dormitory was scaled
badly, two heating elements were completely scaled and no longer useful after
one semester, we had to hire cleaning workers regularly, and the damage rate of
heating elements was extremely high.
When I saw Vulcan products introduced by your distributor-Beijing North Xinhu
Mechatronics Co., Ltd, we doubted if such a simple product could solve our scaling
problem. Let's try and see.
We installed 2 Vulcan to test: one S25 for shower heads in the student bathroom;
one S10 for heating elements of drinking water. After 2 months, no scale was
found on the shower heads, only saw a thin layer of white membrane, and it was
easy to remove. Also, the scale of heating elements were significantly reduced,
Vulcan greatly extends the time of manual cleaning.
Through this test, we are very satisfied with Vulcan products with no doubts.
Strongly recommended!

Following our discussions at the Salon de l‘immobilier Neuchâtelois, we agreed to install the Vulcan
model S100 on our premises for a five-month test phase as soon as our ice period began operating
in August.
The defined objective was mainly intended for the dumpsters of our two ice resurfacers, which are
filled with snow all day long and therefore subject to weekly descaling.
After a few weeks, we noticed that the scale adhered less. This makes it easier to clean our machines,
saving us time and products.
The test carried out allowed us to take the time to compare the positive effects of the Vulcan S100 on
our installation and that the objective set was achieved.
We would like to take this opportunity to thank you for your warm cooperation and extend our warmest
greetings to you, Sir.

Area:

The front door of the station 20, Xian-he oil production plant.
The water inlet of heating furnace.
Installation purpose
The gas heats the water in the furnace, then the hot water heats
the tubes, so that the water temperature in the tubes rises from
40 ℃ to 70 ℃. The water in the tubes passes through the pump,
transported to various wells.
However, the heat exchanger efficiency is decreasing because of
scale in the tubes. More gas has to be used to heat the furnace,
so that the energy consumption is increased.
The calcium (Ca) content in the water is 1469.09 (mg/L), which
is extremely high. The tubes are scaled badly because a variety
of cleaning agents are added constantly and also the tubes are
kept at a high temperature of 60 ℃ -70 ℃. Every 3 months, the
heating efficiency will be reduced down to 50% or even less.
After running 1 year, the whole pipelines and the tubes need
to be cleaned up manually, which is time consuming and costly,
and reduces production capacity.
Therefore, before installing Vulcan, the scale of the tubes was
removed. Then Vulcan S25 was installed to see how it performs.
Installation observation
After installing the Vulcan S25 for 6 months, we found that there
is no additional electricity usage, and the overall heat exchanger
efficiency is still at 80%. We approved Vulcan and will make the
follow-up purchase for the whole project.

Observation: the flow rate with
the Vulcan unit is now even higher
than immediately after previous
manual cleaning had been done.
2. After Vulcan S25 had been installed
for 6 months, the secondary pipes
were opened: scale that had been
left in piping had disappeared and
all 9 secondary pipes had become
clean (see photo).
Observation: Biofilms in the

since the Vulcan unit was installed.
Vulcan S25 was installed around 50
meter before the induction hardening
machine.
►
There are 9 secondary small pipes
with water meters. These meters were
installed to make sure a stable flow

About Huomei Wheel Manufacture Company
Located in Huolinguole Industrial Park, Inner Mongolia.
It is one of the largest aluminum wheels manufacturer
in northern China.
Scaling problems
Before installing Vulcan, adding scale inhibitor
was the only descaling method, and the RO
membrane would be replaced every 2-3 months,
sometimes even more often: every 1-2 months!
Each replacement costs about 9,000 USD.
Results
Since the Vulcan was installed in April 2017, the
RO membrane has not been replaced until now
(October 2017), and the use of scale inhibitors has
also been reduced by 50%. The estimated cost
savings in 6 months has been around 25,000 USD.
After 3 years of Vulcan operation, the results are
still very satisfactory, extending the life of the RO
membrane by about 2-3 times.
A letter from production department of
Huomei Wheel Manufacture Company
From May 2016 to January 2017, 5 sets of RO
membrane were replaced, they cost 50,000 USD.
The issue is urgent.
We found that the problem comes from the water
quality. Suzhou KaiEnSheng recomands Vulcan
for us to try. Surprisingly, the effect is very good.
Vulcan was installed on April 6, the conductivity
after the three-stage RO membranes were: 17.1,
22.7, 21.5 (μ-Siemens/cm) on the day. Over
4 days, we already saw noticeable effect. We
measured the conductivity again on May 4 after
the three-stage RO membranes were down to
11.5, 11.5, and 11.6 (μ-Siemens/cm). We will
keep tracking the effectiveness.

February 2014 - February 2018 (4 Years)
PT Biosolutions Indonesia
Vulcan S500 was located inside aluminum box
and installed on a cooling tower main pipe.
Inspections during the 4 years: 10 times
The photographs show that the refrigeration
condenser tubes, from the beginning to the
end of the trial period, were "as clean as
new".
Please note that for 4 years of 365 days continuous
operation, there has been:
►
• No chemical water treatment.
• No bleed off of waste water.
• No cleaning of condenser tubes.
• No water treatment specialists employed.
First Inspection: March 4, 2014.
The heat exchanger tube plates were
removed to reveal the inside surface of
the copper tubes. Since these tubes had
recently been manually cleaned, virtually
no scale was present, as is on this photo.
Last inspection: February 12, 2018
at the end of the 4-year trial
The inside surfaces of the copper tubes
show zero additional scale formation
after 4 years in the test period.
• Copper tubes in the condensers stay very clean
– without scale.
• No cleaning of the cooling tower inside surfaces.
Summary of Benefits:
• Large savings on chemicals. The complete elimination of chemicals
in this cooling tower operation during the field test supports the fact
that Vulcan is “eco friendly” and would meet the Leeds and Green Mark
Building Criteria required for “Green Building” designation anywhere
in the world. Enjoy the benefits of a world class, sustainable and
“Green” Cooling Tower!
• Huge savings on blow down water consumption. Significant energy
and water savings due to clean condenser tubes and no need
for water blow downs below electric conductivity 10,000 µS/cm
levels with the electronic cooling tower water treatment system –
representing alone a saving of virtually all previously wasted water
due to blow downs.
• Savings on payroll – no operational stoppages required for condenser
cleaning, less testing and fewer inspections needed.
• Savings on supervision – engineers appreciate the “set and forget”
of this automatic water treatment system. Frequency of inspections
and laboratory expenses for cooling tower water testing are reduced
due to the safety and reliability of the electronic systems.
• Scale formation was eliminated. Refrigeration compressors operated
at peak efficiency due to no scale in the condensers.
• Rust prevention in iron pipes is an added benefit of the Vulcan
system.

Each cooling tower has 2 heat exchangers.
Result:
Installed by:
The difference in pressure increased between the
inlet and outlet of the heat exchanger, which showed
a developing blockage.
The heat exchangers had lost in work capacity every
month due to the multiplicity of scale and rust.
5 months after installation, there are no scale issues
in any cooling tower heat exchanger systems.
Due to the excellent results, more Vulcan will be
installed for the rest of the company's facilities in
Israel.

Asia to be awarded the highest level of
Platinum Green Building certification
from LEED (Leadership of Energy and Environmental
Design) that serves as the prototypical building
in Thailand for energy conservation, harmonious
coexistence of industry and the environment and
optimal utilization of resources.
Installation purpose
Before Vulcan was installed, the client used ozone water
system to treat the condenser, but they still found massive
scales in the basin of the cooling towers. They collected
the scales from the basins and weighed them, there were
around 150 kg (average) of scales every month.
The results after 4 months
Vulcan was added together with the ozone system
to treat the water. After 4 months, the approach
temperature of the chiller has been reduced, so that
the energy has been saved from the machine. Also, the
scales from the cooling tower basin have been reduced.
Vulcan S250 and X-Pro 1 were installed on the main
return pipes of the condenser.
7 cooling towers were treated with Vulcan.

Avril Supermarket
Canada
Installation Details
Location: Avril Supermarket
Ville de Laval, Québec, Canada
Model/Area: Vulcan 3000 was installed on the
greenhouse water inlet
Treatment area: 2640 drippers are used to water the entire
production
Scale problem: After 1 year without water treatment,
there was an issue with limestone building
up in the irrigation system which blocked
the drippers; 60% of the entire production
(440 trays of microgreens) did not get an
even distribution of water. It required us
to manually water the unwatered parts of
each tray in order to prevent losses.
Client's feedback: "After 7 months with Vulcan, we’re seeing
a huge improvement in regards to the
even distribution of water. From now on,
manually adding water to the unwatered
parts of each tray won’t be necessary since
there isn’t any! We are totally satisfied with
Vulcan as well as the service."

Testimonial with Jamie Cavey
Hi, my name is Jamie Cavey and I operate the only commercial laundry in Pilbara - the Pilbara
Commercial Laundry Services. We are a mid-size operation that specializes in the laundering of
hotel linen, mine site linen and work clothes.
Living in a hard water area like Pilbara means we have ongoing problems with calcium build up
in our piping and air-conditioning systems. The calcium sticks to the heating elements and the
whole internal section of the hot water system becomes completely clogged with calcium.
Twelve months ago we installed a German made CWT Water Treatment System from the team at
Southern's Water Technology in Bunbury and immediately we noticed a significant reduction in
the build-up of calcium.
I believe we have quadrupled the life span of our evaporated air conditioner and we haven't had
to replace our hot water system for more three years.
Without the CWT Water Treatment System we would be replacing our hot water system every
two years at a cost of more than $10,000.
There is no doubt the CWT Water Treatment System will prolong the life span of your
piping and hot water systems and evaporative air-conditioning units.
After the treatment, the adhesiveness of the crystals is reduced so that scale is unable to form in
the pipes.
You can actually see the calcium slowly breaking down through the drainage system.
Sincerely,
Jamie Cavey

Dear Mr. Kurt,
after a few months testing the Vulcan anti-scale system in our
hygiene center in the station SBB of Basel, we are very happy
with the results. The visible scale deposits are less and the
cleaning is much easier than without Vulcan – with less need of
chemicals. Also the scale depositis of the cisterns and shower
heads are much less, so we have less maintenance costs. We
recommend your Vulcan system and we will install more Vulcan
systems in further of our sanitary stations in Switzerland.
With best regards

CWT - Physical water treatment system
I‘ve been in the plumbing industry for 32 years and currently have five staff working for me at Phillip Best
Plumbing in Western Australia. Since becoming available in Australia, we‘ve purchased a number of CWT
water systems to stop calcium deposits building up in a range of different piping systems. These deposits
create many unwanted effects such as clogged pipes and irreversible damage to pipes and other plumbing
parts.
I found the CWT water treatments to be very effective in high temperature heating systems such as
commercial combustion ovens in restaurants and even in a very high temperature heating system at a local
abattoir. There are also huge time savings associated with CWT water systems. Installation time is cut by
at least 90% when compared to similar units. The units, which are made in Germany, are also at least 50%
cheaper than other units currently on the market.
The units, which allow scale particles to be washed away, are not only proving to be successful in commercial
and industrial applications, but in private homes with scale and rust problems. I installed a CWT system to
protect the hydraulic heating system, which lies under the cement slab of our home.
CWT has been a great cost saving unit initiative that will protect your piping system from ongoing scale and
rust problems.

Dear CWT,
I am a professional cultivator of decorative plants and trees for more than 30 years.
I have always hard water quality problems. This water, I irrigate with it, comes from
a bore. This water is brackish, which means of course, it is very bad for the plants.
Actually, I have been burning my plants all these years because of too much salt.
I also have to emphasize on the fact that all these years the leaves of the plants had
a white color and not the well-known green color. That is of course because of too
much salt of the water.
Installing the Vulcan S25 device, I found out that there is not anymore white
sedimentation on the leaves and soil. Most of all I realize that there is a big
improvement in the growth of my plants. I also found out that there is a better and
quicker foam creation. Wherever we want to wash our hands or even clothes etc.
Finally, I must say that I really found the solution to my problem, which has been
bothering me for all these years, using the Vulcan device.
I really have to thank you from the bottom of my heart.

Dear Mr. Christiani,
Thank you a lot for sending me the stronger electronic system, which I installed immediately. I noticed
that the drinking behavior of the animals improved promptly. I can give you more details after a longer
observation period. Now about the promised observation of the CWT water treatment device:
After 2-3 days of the installation, it was remarkable that the lactating cows were permanently drinking
from the drinking trough and that therefore the milk production also improved after 14 days, which
again led to higher weights of the piglets (before: ca. 7 kg, now: 8 kg). This continued for several
months.
Furthermore, we observed that scale and biofilms in old pipes for liquid feeding dissolved, leading to
an improved feeding behavior of the fattened pigs. Moreover, we used to have trouble with flank
abscesses due to biofilms that were probably caused by bacteria discarding endotoxin. This
progressively improved with the use of CWT water treatment.
I can also tell you about a cow farmer whose pipes were not clogged anymore after the installation of
CWT products. Before, he had to flush the pipes every 4 weeks with air and water to make sure the
cows could get enough water through the pipes. He could furthermore observe that the biofilm on the
high-alloyed steel drinking trough dissolved after 14 days. After about 4 weeks, the farmer also
reported that the cows produced about 0.5 L more milk per day.
Negative observations:
The next year in February, I started to occasionally add acids in the tubes with the consequence that
the positive effect of the CWT water treatment mostly vanished. Furthermore, new biolfilms built up in
the pipes, which I could make visible by flushing the pipes. The animals began to show more flank
abscesses and ear necrosis again. This improved again after the flushing in the beginning of June.
Then, on 19 July, I installed the stronger electronic system. Since then, I have the feeling that the
livestock has stabilized and has become more vital.
I hope I can give you more positive news soon and that I can tell you, whether an occasional addition
of acid to the water system is possible without damages, since it is common practice to use acidy
products in farms holding pigs and turkeys.
Please don’t hesitate to contact me for further questions.
Best regards,
Hubertus Fasselt

Review of the VULCAN equipment
Installation location: Main water feed of Mother and baby convalescent home ― Telshe Stone.
System installed: VULCAN S100
The system was installed on our main source of water supply in the main water supply to the building.
Before installing VULCAN, we treated the scale with water softeners, which required large amounts of salt,
cleaning and maintenance.
► For dishwashing systems, hot water for showers and washing machines we used salt softeners.
► Drinking water boilers and kettles in the wards required weekly cleaning with tartaric acids.
► Shower heads needed frequent treatment to remove scale deposits.
After installing the VULCAN system:
► We have stopped consuming acids to clean the drinking water containers. They can now be cleaned by hand.
► Water softeners have been taken out of operation and no more salt is used!
► The dishwashers are clean!
► The shower heads < After a period of cleaning all the pipes > do not need cleaning and no replacement is
required.
Savings:
► In cleaning materials, filters, maintenance time, and not needing to stop the use of facilities just for the sake of
cleaning the water systems.
► Financial savings: the price of a VULCAN system is covered within a reasonably short period of time.

Results before and after the Vulcan installation
Kitchen Kettle
Before (without Vulcan): A layer of scale had accumulated at the
bottom over time, it was impossible to remove it with a plastic spatula.
We could only leave vinegar to let it act for a long time, so that the
scale could be removed.
After (with Vulcan): Scale is easy to be removed, even with a
finger or a damp cloth.
External surfaces of pots and pans
Before: If you do not wipe off water right away, the water would leave
spots and it would be difficult to remove afterwards. You can only
clean with dishwashing detergent again, and wipe off water without
delay.
After: Even the pot has been dry for 30 minutes, it is still easy
to remove spots with a damp cloth. If it is left to dry for a longer
period, e.g. 1 night, the spots disappear after rubbing the surface
for several times with increased pressure but still without
detergent.
Sink (stainless steel)
Before: Quick greasy fouling, especially after removing residues from
cooking oils with rinse water from cooking tools. Rough sponge and
brush with degreasing detergent needed.
After: The degreaser is still necessary but the cleaning is easier
and less work.
Dishwasher (internal wall is stainless steel)
Before: White layer of scale adherent (on the bottom and on the door)
was difficult to remove; anti-scale product was required.
After: The white powder on these surfaces is easy to remove
with a wet sponge (no special cleaning product).
Chrome faucet
Before: Scraping scales with a knife onto the spay heads was necessary
because the outlet holes of the spay heads were stuck by scales.
After: If scale builds up on these elements, it can be easily removed
without an anti-scale product.

Garden Sprinkler Systems
Australia
LANCE BUTCHER
Gelorup
Western Australia
Water treatment system by CWT Germany
My wife and I live on a 5 acre property at Gelorup, 20 minutes south of Bunbury in Western
Australia. Our local water causes enormous problems with our reticulation system. Large quantities
of iron sludge and chips would build up in the piping system and block the solenoids and individual
sprinklers. The situation was getting us both down. It seemed like the sprinklers were continually
blocked and I was replacing the solenoids every six months.
Within three months of installing the CWT water treatment system the rust residual and sludge disappeared.
I was staggered by the results. The pipe was completely clear and there were no signs
of the iron scale at all.
A reliable and clean sprinkler system is very important for us to maintain a healthy garden which contains
more than 200 rose bushes and half an acre of trees and cottage garden. Our horse paddocks are also
under reticulation. The CWT system has saved me an enormous amount of time and money and I’m no
longer cleaning sprinkler heads or replacing the solenoids in the reticulation system.
The results have been so successful we are now planning a major expansion of the
garden and bird aviary. I would recommend this product for anyone who lives in a hard water area
in Australia. They’re simple to install and maintenance free.

Hairdresser Recommendation Letter

Hairdresser Claudia Gugler‐Roux
3182 Ueberstorf, Switzerland
www.coiffureclaudia.ch
Recommendation Vulcan Ueberstorf, November 2011
In the course of my almost 25 years of career as an hairdresser, I have been dealing with the element of water every
day. That is exactly how long I have been searching for a method to reduce lime deposits.
For 10 years now I have been running my business in my own house. All the more I was interested in doing something
against the constant cleaning and descaling in the household. Furthermore, the whole family prefers tap water as
their main drink. So the quality of the water is very important to us.
Vulcan sounds very interesting and I decided to install such a device for a test.
After we have been using Vulcan for half a year, we can make the following positive observations:
Less limescale deposits in shower, bath, WC.
Easier cleaning of our glass shower cabin (considerably less limescale deposits).
The water is noticeably softer, which is noticeable when washing my customers' hair.
The drinking and tap water is of a higher quality. It is noticeably more velvety and tasteless.
Taps and nozzles are less calcified.
The coffee machine is hardly calcified any more.
Generally less consumption and use of conventional descaling agents.
All in all only positive findings. We bought the Vulcan with complete conviction. If the statements also apply to the
water pipes in the house, our water pipe system will not incur any expensive maintenance costs in the next few years,
so that this investment has also paid off here.
Addendum 27.05.2020: Even after 9 years I am still very satisfied with Vulcan and am happy to give my consent for the
publication of this reference.

The good comments of the director of the residence:
After 1 year of use, the results are positive, the cleaning
of limestone in kitchen appliances has decreased by 75%.
We have done tests on the filters in the kitchen, we stopped
changing the kitchen’s water filters in 2018 when installing
the Vulcan system. In 2020, the old filters of 2018 are made
immaculate white as if they were new, we can affirm that
the Vulcan system makes it possible to stop filter
changes, with a fairly high efficiency that the Vulcan
system was used to clean the old filters clogged.
We also noticed a complete stop of the service calls
concerning the limestone in the showers of housing. Before
the Vulcan system, we had to clean the shower heads in
each of the homes every 16 months. Since the installation
of the system, no customer has requested service for
cleaning.
In summary, we are completely satisfied with the system,
and we can say that customer service and water quality
have been greatly improved.

Concerning the effect of the water-treatment device

Test subject: water treatment device "Vulcan 5000"
Manufacturer:
Christiani Wassertechnik GmbH (CWT)
Heinrich-Heine-Str. 15
D-52249 Eschweiler
Test instruction:
A test should be carried out to determine whether Vulcan 5000 can reduce lime
deposits in water pipes and household equipment in a purely physical manner
without altering the water chemically.
Experimental demonstration of function:
The effect was verified in a heat exchanger arrangement using two identical testing
units. Water was withdrawn from the water pipes simultaneously upstream and
downstream of the device to be tested and calcium precipitation forced in the heat
exchangers.
As lime deposits increase, the flow of water decreases. The more water flows
through the experimental arrangement, the smaller tendency there is for the water
to form scale on pipes and container walls. The test was carried out on the basis of
the practice-related water withdrawal of a four-person STEINBEIS-STIFTUNG household FÜR with the additional
WIRTSCHAFTSFÖRDERUNG
regular withdrawal of five litres of water at half hourly intervals for a total of six weeks.
(Foundation of economic promotion Reutlingen)
This test showed that the tendency to form lime deposits is reduced considerably by
the “Vulcan 5000” water-treatment device. In addition, the effect continues for some
days after “Vulcan 5000” has been switched off. Seemingly, the effect is not only
limited to a certain part of the pipe, but also passed into the water flowing nearby
sections of the pipe.

Residential Client from Bünde

Dear Ms. David,
I would like to take this opportunity to thank you once again for the great offer to test your
Vulcan 3000 for six weeks.
My results ...
The device was very easy to install on the water pipe.
After plugging in the power supply, it was ready to go.
And how it started....
After just two days (by which time the water in the hot water tank had almost been
replaced), the limescale deposits in the bathroom (glass door and fixtures) were noticeably
reduced. We could also notice positive effects of the „lime converter“. Hardly any deposits
in the black kettle and coffee maker. Another positive point is that you have the feeling of
softer hair after showering.
What can I say, that device meets our expectations to our complete satisfaction.
Thank you very much.
With best regards
Jürgen Bartelheimer

First-hand report concerning the Vulcan 5000 electronic water treatment system
Dear Mr. Christiani,
We would like to in the following share our experience with the VULCAN 5000 device.
We installed the VULCAN 5000 device for a trial period back to last year. As the results of the device
during the trial period were positive and conformed with our decalcification requirements, the only
thing preventing us from making the purchase immediately was that we were waiting to test two
further devices.
The other two devices which were based on magnetism could not maintain the same results achieved
by the VULCAN 5000. The effect of one device was incomparable, the other device was difficult to
assemble due to incorrect dimensions. Since our family house is an old building with an extension
built in 1991, the water pipelines are so laid out that the distance from the wall to the centre of the 1
inch supply line is only 25mm. Despite this narrow width the installation of the VULCAN 5000 device
was not a problem.
After we sent back your device and the other two shortly after, we put off the issue of water softening
and decalcification. However, after visiting the ‘Heim & Handwerk’ trade fair in Munich this year, we
decided to purchase your device, due to our high water hardness.
Since the installation we have noticed the immediate effects of softer water as well as a decrease in
the amount of scale. The reduction of scale is particularly visible in the transparent water container
of our espresso machine as well as in the aerators. We are confident that we have purchased the
correct device for our house with a good price/performance ratio.
Yours Sincerely,
Family Janker
